    I'm trying to play back a blu ray disc in my Panasonic internal blu ray drive via Power DVD Ultra on windows and i'm getting stuttering video and audio. For some reason it seems like windows is the problem. I get image and sound fine. But after a second or two of playing it begins to stutter and plays slow frame by frame.

    I have an early 2008 17" macbook Pro with 4GB ram 2.6 core 2 duo and an nvidia 8600GT with 512MB of ram.

    You will probably have to post in the windows on mac section for help on this issue. Most likely a windows driver or codec issue.

    Cheers,

    How fast is your player? Are you sure that it's in DMA and not PIO mode? Have you installed Intel ICH drivers?

    I talked to a friend, and he said that the drive needs to be able to work in Ultra DMA mode. Is the 2008 non unibody MBP capable of Ultra DMA mode with its optical drive?

    Yes. All Sata devices (disks and superdrive) work in udma mode in windows. I had the same problem on my windows desktop with my DVD-R. I installed intel SATA matrix drivers and it was cured.
